PHILADELPHIA (CBS) — An electrical problem is to blame for a delay in the delivery of today’s Inquirer and Daily News.

Interstate General Media, which owns the papers, say there is up to a four hour delay in getting the paper out to readers and some may not even get a copy Saturday.

“We had an electrical surge occur very late Friday night and into the early morning hours,” explained Mark Block, spokesman for Interstate General Media. “Which impacted the transmission of the copy and the photos for the Philadelphia Inquirer and the Philadelphia Daily News weekend edition.”

The newspapers are headquartered in Center City, while the printing plant is in Conshohocken. Block said that they are trying to get the papers out to as many of its readers as possible but, “in some instances no delivery, depending on where they’re located.”

In that case, Block says the Saturday edition will come Sunday.

“We expect to be back in full capacity with Saturday behind us and Sunday’s edition delivered on time,” he said.
